Embodiment 1
[0040] First, the artificial aggregate is subjected to sandblasting, and then the artificial aggregate is soaked in the first acid liquid sulfuric acid (concentration: 95 to 99%) at a temperature of 100 to 120°C for 5 to 60 minutes, followed by ultrasonic vibration Machine, using pure water and alcohol as the medium to clean and wet the artificial aggregate, after that, soak the artificial aggregate in the second acid liquid hydrochloric acid (concentration: 36 to 40%) at a temperature of 80 to 100°C5 minutes to 60 minutes. Then, an ultrasonic oscillator is used to clean and moisten the artificial aggregate with pure water and alcohol as the medium, so as to obtain the artificial aggregate after surface treatment.
[0041] The surface roughness of the artificial aggregate obtained in Example 1 was measured with an optical three-dimensional surface roughness measuring instrument, and the results are shown in Table 1. The surface roughness of the artificial aggregate obtained i...
Embodiment 2
[0048] The specific steps are the same as in Example 1, except that the first acid solution used is hydrochloric acid (concentration is 36 to 40%), the treatment temperature is 80 to 100°C, and the soaking time is 5 minutes to 60 minutes. It is sulfuric acid (concentration of 95 to 99%), the treatment temperature is 100 to 120°C, and the soaking time is 5 minutes to 60 minutes.
